Notes on the geology of the upper Ooddvnri basin, between the River Wardha and. the 
Godavari, near the Civil /Station of Sironcha, by Theodore W H. Hughes, 
A.R.S.M., F.G.S., Geological Survey of India. 
In the Memoir on the Wardha valley coal-field, an arbitrary lino along 19° 
30' north latitude was adopted as the southeim limit of the field, there being 
in that direction no definite geological boundary of contrasting rooks within 
the geographical confines of the Wardha valley. The same series and groups, 
in fact, stretch continuously to the south-east beyond the Wardha field, down 
the adjoining valley of the Pranhita and that of the Godavari, for more than 
230 miles, thus making one great geological region, embracing a large portion 
of the drainage area of three distinct and important rtvers. This region, 
which, towards the north, has mainly been surveyed by Mr. Fedden and 
myself, has, towards the south, been under Mr. King’s care. We have now 
brought our leading geological line.s from each side to the Godavari river, and 
there only remains the work of investigating the slight difference that must 
neoessai’ily have arisen when observers start from widely separated points. 
This duty Mr. King undertakes next season. 
My most recent field notes refer to the district between the Wardha valley 
and the Godavari (from Naspur to Sironcha), an area that ha.s up to this time 
been only cursorily examined. 
I was able to distinguish in descending order the— 
Trap series— 
Cliikiala group 
Kota-Maleri „ 
Kamtlii „ 
Barakar „ 
Talehir „ 
Vindhyan series. 
Metamorpliic series. 
A.— Metamorphic and Vindhyan Series. 
The rocks of the mctamorphic series were found always exterior to the 
Gondwana area. With one exception this is also the case with the Vindhyans ;
